Graphs May Prove Key in Search for Holy Grail of Quantum Error Correction

Current quantum computers, utilizing technologies like the trapped ion device on the left, are beginning to tackle problems theoretical physicists care about, like simulating particle physics models. More than 60 years ago, the physicist Julian Schwinger laid the foundation for describing the relativistic and quantum mechanical behaviors of subatomic particles and the forces among them, and now his namesake model is serving as an early challenge for quantum computers.

A curved and stretched sheet of graphene laying over another curved sheet creates a new pattern that impacts how electricity moves through the sheets. A new model suggests that similar physics might emerge if two adjacent universes are able to interact. (Credit: Alireza Parhizkar, JQI)

In new numerical experiments, quantum particles (black dots), which travel upward through time, are subject to random quantum processes (blue, green and yellow blocks). Depending on the likelihood of the different kinds of processes, the quantum particles ultimately end up in different entanglement phases. This figure shows five examples of randomly chosen processes acting on a small number of particles. (Credit: A. Lavasani/JQI)
